About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, raw graphics performance, VRAM, feature set, power efficiency, pricing context, and long-term value so you can see which GPU actually makes more sense.

GeForce GTX 645

2010

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 12.5 vs 0 G3D/$ ($150 MSRP vs Unknown MSRP).
  • 100+% more VRAM for high-resolution textures and newer games (1 GB vs Unknown).

Trade-offs

  • Very weak future-proofing: 2010-era hardware with 1 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
  • 1233.3% higher power demand at 200W vs 15W.

Radeon RX Vega 11 Ryzen 5 3350G

2020

Why buy it

  • Draws 15W instead of 200W, a 185W reduction.
  • More future proof: Vega (2017−2020) on 7nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with Unknown vs 1 GB for high-resolution textures and newer games.
  • Very weak future-proofing: 2020-era hardware with Unknown of VRAM is already obsolete for modern gaming and is hard to recommend today.
  • Lower G3D Mark per dollar, at 0 vs 12.5 G3D/$ (Unknown MSRP vs $150 MSRP).

Quick Answers

So, is Radeon RX Vega 11 Ryzen 5 3350G better than GeForce GTX 645?
Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 1,880 vs 1,898 in G3D Mark. The bigger reason to prefer Radeon RX Vega 11 Ryzen 5 3350G is the overall package: you are getting a newer generation, FSR upscaling, plus much lower power draw (15W vs 200W).
Which one is more future-proof for 2026 and beyond?
GeForce GTX 645 is the more future-proof choice for 2026 and beyond. You are getting more VRAM at 1 GB instead of Unknown and the stronger feature stack with no meaningful modern upscaling stack instead of FSR upscaling. That extra memory headroom makes it the safer pick for newer games, heavier textures, and higher settings over time.
Which one is the smarter buy today, not just the cheaper card?
Radeon RX Vega 11 Ryzen 5 3350G is the smarter buy by a wide margin. Radeon RX Vega 11 Ryzen 5 3350G is priced in an unclear MSRP range at an unclear MSRP versus $150 MSRP, and you are getting 1.0% higher G3D Mark. GeForce GTX 645 really only makes sense now as a very cheap stopgap or a used-market placeholder.
When does GeForce GTX 645 make more sense than Radeon RX Vega 11 Ryzen 5 3350G?
Yes. GeForce GTX 645 is still an excellent gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It makes more sense if your priority is future-proofing and staying closer to $150 MSRP more than squeezing out the extra headroom of Radeon RX Vega 11 Ryzen 5 3350G. The trade-off is that Radeon RX Vega 11 Ryzen 5 3350G currently gives you 1.0% higher G3D Mark. GeForce GTX 645 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
